单侧唇腭裂(UCLP)患者的颌面异常表现在不同程度的上颌骨发育不足,常伴有残余口鼻瘘、牙槽骨缺陷和软组织疤痕。此外裂侧侧切牙常先天性缺失。为有效处理UCLP的上述异常,作者对Le Fort Ⅰ型截骨术进行了改良。 手术原则与方法 ①软组织切口的改良:除水平切口外在齿槽突裂处设计垂直形切口,以便更好的暴露、截骨、关闭口鼻瘘、植骨和固定,而不影响截骨段血 Maxillofacial anomalies in patients with unilateral cleft lip and palate (UCLP) are manifested in varying degrees of maxillary hypoplasia, often accompanied by residual oral and nasal fistula, alveolar bone defects and soft tissue scars. In addition, the lateral cleft incision often congenital absence. In order to effectively handle the aforementioned abnormalities in UCLP, the authors modified Le Fort Ⅰ osteotomy. Surgical principles and methods ① improvement of soft tissue incision: In addition to horizontal incision in the alveolar cleft at the vertical incision designed to facilitate better exposure, osteotomy, mouth and nose fistula closure, bone graft and fixation, without affecting the osteotomy segment blood
